A demilitarized zone is an area in which treaties or agreements between states, military powers or contending groups forbid military installations, activities, or personnel. A DZ often lies along an established frontier or boundary between two or more military powers or alliances. A DZ may sometimes form a de facto international border, such as the Korean Demilitarized Zone. Other examples of demilitarized zones are a 14 km (8.7 mi) wide area between Iraq and Kuwait; Antarctica ; and outer space.

Korean Demilitarized Zone
The Korean Demilitarized Zone is a heavily militarized strip of land running across the Korean Peninsula near the 38th parallel north. The demilitarized zone (DMZ) is a border barrier that divides the peninsula roughly in half. It was established to serve as a buffer zone between the countries of North Korea and South Korea under the provisions of the Korean Armistice Agreement in 1953, an agreement between North Korea, China, and the United Nations Command.
